The foreign ministry expressed its concern about the humanitarian situation and disregard for the lives of thousands of civilians.
The appeal on Tuesday came as Sri Lankan forces were continuing their offensive against Tamil Tiger rebels in the northeast of the country.
The military operation gathered speed after the rebels ignored a deadline to surrender in one of Asia's longest-running conflicts.
The Swiss-run International Committee of the Red Cross has warned of a catastrophe and urged both sides to prevent further mass casualties among civilians.
Over the past few weeks Tamils have been staging demonstrations in cities worldwide, including the Swiss capital, Bern, to protest against the offensive.
